Champion queue trading system

Many times have i been in a queue where someone asks someone else higher in the queue to save their 'OP' Champion for them. and a couple of games where they just want to trade for fun or to throw off the other team. now this doesn't seem like a big deal but because of this people have been failing to trade. whether it be because they are a troll, Want to play the champ for themselves, or plain leave their computer and forget to trade. Recently this happened 3 times in a row to me and caused me to be demoted to silver 3. i had just finished my 10 promo games and was placed in silver 2 i won a few games then the trading hell started. because in 2 of the 3 games the people afk'd, riot said that in my next promo series they'd give me a free win. so here are things that need to be fixed (In my opinion). 1, Trading system needs to be removed. When your in a game where do you see people just trading for the hell of it because they want to play each others champions. its only when they want a champ saved or they are friends wanting to trade for the hell of it. i know it probably wont get removed. but it should have its limits. it should be like aram re-roll. you should only get one if you play enough games and win it. and the person that makes the trade pays for it and if the other person declines then the trade point is refunded. this would cut down on the trolls and afk'ers in league. 2, Demoting system due to afk's. Riot should have all games monitored by bots and if in a ranked game if the team has an afk for longer than 15 minutes they should have the LP loss be reduced to about 5 per game and 8 if they are on a losing spree. and if the person has 0 LP at the start of the game and they have an afk, they shouldn't be demoted. And the person that afk'd should lose double the LP whether the game is a win or loss. because when a team wins a 4v5 that afk person gets freelo. and that is annoying just as much a losing with an afk. 3. Chat should also be monitored so that if a team is losing someone doesn't just say 'ima afk so you guys dont lose as much LP', and anyone that flames in a game should be muted for a period of time. because communication is key in league and ignoring people doesn't help when you need to talk to your ADC as support but hes flaming you. with the ability for riot to mute toxicity for about 5 minutes might bring down the amount of toxicity on the rift because people wont want to just not be able to talk. While all of these are just my opinions on what riot should do, i doubt they'll actually read this or even care. but something needs to be done with the amount of control players have on the rift. because it takes one person to tab out for a game to be over.
